The Water Quality Index (WQI) is an important parameter in describing the water resources' suitability for human uses and one of most effective methods quality indicative assessing utilization health ecosystems. WQI Canadian Council Ministers Environment (CCME) was used study to describe Shatt al-Arab Basrah Southern Iraq, its drinking use. data analyzing river samples were adopted from five st...

fuzzy water quality index (fwqi) was applied in order to assess the degree of drinking water resources in yazd province, iran. thisstudy has also offered the creation of a new fuzzy water quality index (fwqi) to evaluate this tool’s applicability. 12 chemicalparameters including toxic and non-toxic heavy metals measured in 71 groundwater samples collected from drinking water resourcesin rural a...

abstract the effect of land use type on soil functioning within an ecosystem can be assessed and monitored using soil quality attributes. such studies, which are carried out to create a balance between the biological production and the maintenance and improvement of land resource quality, provide a framework for land degradation control and also for identification of sustainable management. in ...

The cytochrome c maturation protein CcmE is an essential membrane-anchored heme chaperone involved in the post-translational covalent attachment of heme to c-type cytochromes in Gram-negative bacteria such as Escherichia coli. Previous in vitro studies have shown that CcmE can bind heme both covalently (via a histidine residue) and non-covalently. In this work we present results on the latter f...

Biogenesis of c-type cytochromes in alpha- and gamma-proteobacteria requires the function of a set of orthologous genes (ccm genes) that encode specific maturation factors. The Escherichia coli CcmE protein is a periplasmic heme chaperone. The membrane protein CcmC is required for loading CcmE with heme. By expressing CcmE (CycJ) from Bradyrhizobium japonicum in E. coli we demonstrated that hem...

Abstract River is one of the surface water resources used to meet people’s need for daily clean water. Along with population growth, problems related waste produced are also increasing and causing environmental pollution, including river pollution. sustainability issues that has attracted attention various institutions, which Citarum sources raw people in West Java. In this study, analysis cond...

Abstract The quality of the drinking water source reservoirs has always been a research hotspot. However, few have studies focused on over relatively long period with time series analysis. In this paper, based and hydrological data from 2010 to 2020, considering 8 parameters, CCME-WQI analysis was used explore interannual seasonal changes in Weishui Reservoir. Furthermore, main factors affectin...
